“…signals of opportunity (SOOP). Navigation using SOOP is to make use of all RF signals in sight for navigation [9,10] . Signals of opportunity include other signals which are not designed for navigation specially, for example, TV [11,12] , AM, FM [13,14] , Bluetooth, Cellular, WiFi, Wimax, aviation wireless data link and etc., besides GPS, Galileo and GLONASS signals.…”

In the complex lower airspace embraced by mountain, Global Positioning System can't take action because navigation signals are easily shaded by barriers. Signals of opportunity (SOOP), i.e. other RF signals in airspace, can be used for positioning to improve availability. In this paper, for alternative TV, Cellular, WiFi, RFID, aviation data link besides GPS, physical advantages and disadvantages are analyzed, including their application. Based on requirements for complex lower airspace, proper SOOP are chosen. Navigation positioning methods of SOOP is presented, such as TDOA (time difference of arrival), AOA (angle of arrival) and RSS (ranging signal strength). Then the positioning manners can be confirmed according to the complex lower airspace. Lastly, problems for SOOP in complex lower airspace are concluded.

An emerging challenge in the design of interfaces for mobile devices is the appropriate use of information about the location of the user. This chapter considers tradeoffs in privacy, computing power, memory capacity, and wireless signal availability that accompany the obtaining and use of location information and other contextual information in the design of interfaces. The increasing ability to integrate location knowledge in our mobile, ubiquitous applications and their accompanying tradeoffs requires that we consider their impact on the development of user interfaces, leading to an agile usability approach to design borne from agile software development and usability engineering. The chapter concludes with three development efforts that make use of location knowledge in mobile interfaces.
